Another instance of Certbot is already running - Solved - Linux guru

Image source certbot

Certbot is a free and open-source software tool for automating the acquisition and renewal of SSL/TLS certificates. SSL/TLS certificates are cryptographic certificates that enable secure communication between a website and its users. The Electronic Frontier Foundation (EFF) created Certbot, which is widely used in the industry.

 

I got this error while configuring SSL on my website using certbot. So here is the steps which i used to resolve this `Another instance of Certbot is already running` error.

Error :

Another instance of Certbot is already running

certbot --server https://acme-v02.api.letsencrypt.org/directory --manual --preferred-challenges dns  --installer nginx -d *.vishalvyas.com

Another instance of Certbot is already running

Reason :

when you run certbot form your machine and unexpectedly stop the command, Then cert bot is not running but it left some .certbot.lock files behind.You need to kill the certbot instance form your machine.

Solution :

• Run the below command to find killed certbot.

find / -type f -name ".certbot.lock"

You can see result of the command, If there are, you can remove them.

• Run below command to remove them.

find / -type f -name ".certbot.lock" -exec rm {} \;

And then try again. I hope your issue has been resolved.You can read more articles on my blog about Let's Encrypt configuration for Nginx and for Kubernetes SSL.
